I get that all the time from my mum, who has been T1 since before I was born. When my daughter was diagnosed, I explained to her how the pump works because I thought she was interested, but all we get is “you’re testing too often” and “puddings should be banned” and “you’re saying the only reason her HbA1c is better than mine is because she uses more insulin?” (That last one said in a very accusatory tone as if it’s somehow wrong.) Etc etc. I’ve tried dropping heavy hints that we’ve been taught a different way from her and we’re happy with how it works, if she’s happy with how she does it that’s fine, there’s more than one way of doing things and we all have to find what works best for us and then stick to that and forget what everyone else is doing. But it still doesn’t work, I have to just try and ignore her now

I think she’s jealous because she’s always been told that she can’t have puddings and sweet things, and then sees my daughter eating whatever she likes and getting better results into the bargain. But she doesn’t want to learn how it’s done, she could carb count like we do even on injections but sticks rigidly to her fixed doses and doesn’t want to know. Which is fine, but stop moaning then, either learn how to improve things yourself or stick to your favourite way and have the decency to let us do ours!
